Dynamic metal-metal cooperation in chemical reactions — •Jana Roithová — Radboud University, Nijmegen, The Netherlands

Textbook descriptions of organometallic reaction mechanisms typically feature metal complexes with a single metal atom. However, these reactions frequently also give rise to polymetallic complexes, which can be crucial in the processes under study. Incorporating multiple metals renders the mechanistic explanations less straightforward and more complex, leading to the frequent exclusion of polymetallic complexes in such discussions. Many researchers tend to limit their mechanistic models to mononuclear complexes, often resorting to less favored oxidation states or high-energy steps. In my presentation, I will explore how the dynamic formation and disintegration of bimetallic complexes can facilitate these reactions, circumventing steps that are otherwise unfavorable.
